Not able to ssh or ping a server

UNIX AIX
1

Hi,

Earlier I was able to ssh /ping the server but now it just hangs

Please suggest how to troubleshoot.

Best regards,

Tell us about the network between you and it.

I'd try traceroute as the next step.

Just hangs (how long, btw?) ... or displays some error msg?

If you have root password or an aix admin,
Take console of the server and check for process which are consuming more memory, if its not critical or it wont affect the production. kill it !!!

Then for ping issue,
Check the routing table netstat -nr
if you found duplicate default value of first two rows delete one.

For SSH,
stop and start the sshd daemaon.

Thanks,
Thala
